Enabling Performance in the Design of Hydrogen and CNG/LNG Mobility Solutions

Enabling Performance

Designing clean energy production, distribution, compression, refueling, and mobility solutions is uniquely challenging. As an example, hydrogen can embrittle and degrade many lower-quality metals and can be hard to contain under pressure. High pressures, rapidly changing temperatures, and persistent vibration all pose challenges to fluid systems and infrastructure. Our engineers can help by recommending or constructing fluid system components and assemblies configured to your requirements.

  • Our standardized, configurable fluid system assemblies are thoroughly tested, inspected, packaged, and warrantied. Single part numbers also make ordering easy. All assemblies are built according to best practices through our design and assembly services.
  • Our experienced product design engineers have the technical knowledge, advanced software, and manufacturing expertise to customize fluid system products to meet narrow specifications. They can help with applications such as fuel line integration, priority panels, dispensing systems, heavy-duty refueling equipment, and more.
  • Our materials scientists can apply an expert-level understanding of metallurgy and chemical compatibility to help you find the right materials and designs despite any challenge. Minimize corrosion, hydrogen embrittlement, and other issues by working with specialists to choose fluid system components that have all the appropriate certifications, approvals, and compositions already in place.
